deadline option of lease not work

[zyf0330]

I connect to remote etcd and set deadline +4s for lease call, but it cost 1 min to give error 14 UNAVAILABLE: failed to connect to all addresses. Socket keeps SYN_SENT state from ss -tpn.
The option dialTimeout for ETCD3 constructor doesn't work too.

I don't hit this; if I write something like

const { Etcd3 } = require('./');

const etcd = new Etcd3({ hosts: ['127.0.0.1:3464'] }); // nothing is on this port

const now = Date.now();
etcd
  .lease(60, { deadline: new Date(now + 1000) })
  .grant()
  .then(() => console.log('grant'))
  .catch(err => console.log('error', err, 'after', Date.now() - now));

I get output like

error GRPCDeadlineExceededError: 4 DEADLINE_EXCEEDED: Deadline exceeded after 1057

Maybe you should try a remote host not localhost. Network detect strategy is different between them.

This just happes when remote host port is at filtered status. And after 30s or 60s it gives error "14 UNAVAILABLE: failed to connect to all addresses".
If remote host port is an opend service which is not etcd service, it gives error "2 UNKNOWN: Stream removed" and elapsed time depends on how long server closes this connection.

So I think the root cause is dialTimeout doesn't work and it should decide this timeout. I doesn't find code implement of option dialTimeout
